'Disguised' in the Bible

So she removed the clothes of her widowhood and covered [herself] with the veil and disguised herself. And she sat at the entrance to Eynayim, which [is] on the way to Timnah, for she saw that Shelah was grown but she had not been given to him as a wife.

As soon as Joseph saw his brothers, he knew who they were, but he remained disguised and asked them gruffly, "Where are you from?" "From the land of Canaan," they replied. "We're here to buy food."
